Title: Manufacture of semiconductor device
Inventor: SHIMAZAKI TOYOYUKI
IPC: H01L21/31
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the occurrence of a cavity and to obtain a semiconductor device capable of corresponding to the microscopical formation of a pattern by a method wherein, after an Si oxide film is formed, the upper parts of cavities are opened and a heat treatment is conducted while a temperature is made to rise stepwise in a high-tempera ture vapor phase atmosphere. CONSTITUTION:The pattern of a poly Si film 2 is formed on a semiconductor substrate 1 and an Si oxide film 3 is deposited thereon. Then, when the surface of the film 3 is etched with a mixed solution consisting of an ammonium fluoride and a hydrofluoric acid, the upper parts of cavities are opened and deep grooves 4 are formed. Subsequently, when a heat treatment is conducted while a temperature is made to rise continuously or stepwise in a high-temperature and nitrogen containing atmosphere, a good flatness is obtained. Moreover, after a flattening treatment is conducted, a metal wiring 5 consisting of Al is provided. Phosphorus, boron or arsenic or one of phosphorus and boron is made to contain in the film 3. Thereby, the generation of a cavity in the oxide film and the disconnection of the metal wiring are prevented and a semiconductor device capable of corresponding to the microscopical formation of a pattern is manufactured.

Title: Brazing method for metallic member having nitrided layer on surface and brazing filler metal for welding used therefor
Inventor: KUGA NORIYOSHI
IPC: B23K1/00
Filed: 1993-03-31
Abstract: PURPOSE:To inexpensively improve joining strength in a brazed product of the metallic member having the nitrided layer on the surface having high wear resistance. CONSTITUTION:Brazing filler metal added with Al or Cr or Al and Cr by 0.5-3% at the weight rate on brazing filler metal consisting essentially of Ag-Cu or Ag-Cu-Zn is produced. The other member to be joined (printed wire) 2 is brazed on the metallic member (printed lever) 1 having the nitrided layer 1a on the surface by using this brazing filler metal. Since Al or Cr easily combines with Ni in the nitrided layer and molten brazing filler metal 3 is improved on wettability for the nitrided layer, this is stuck to the surface of the metallic member extending over the wide range. The nitrided layer which has been executing a cohesion suppressing function between the metallic member and the molten brazing filler metal is extinguished by using this brazing filler metal and a layer where a compound of N in the nitrided layer with Al or N with Cr is diffused is produced. As a result, an affinity between the metallic member and the molten brazing filler metal becomes higher, bubbles in the molten brazing filler metal are removed and strong joined surface is obtained.

Abstract: PURPOSE:To enable detecting the deviation from the route of an important article transporter car by transmitting the result of defining the present position based on the transmission wave from a global positioning system (GPS) satellite to a mother station and comparing it with a route set in advance. CONSTITUTION:The signal from a GPS satellite 23 is sent to a controller part 2113.

To the processor three kinds of master files, for example, hard disks are connected. In the mother station 22, the deviation of the sent present position of the car 21 from the running route set in advance is calculated and when the deviation exceeds a predetermined threshold, alarm is generated.

Title: Continuous casting method
Inventor: KITAOKA HIDENARI
IPC: B22D11/10
Filed: 1988-03-30
Abstract: PURPOSE:To prevent trap of blow hole and non-metallic inclusion into interface between solid and liquid by giving a cast slab within the specific distance at lower part of meniscus ultrasonic vibration. CONSTITUTION:Molten steel 1 is poured into a mold 6 from a tundish 2. Inert gas for preventing nozzle clogging is blown from a piping 4 into a stopper 3 for controlling the flow rate or a submerged nozzle 5. The ultrasonic vibration is given to solidified shell 10 from ultrasonic impressing rolls 7 fitted just below the mold 6. Amplitude and frequency thereof are applied at the prescribed suitable values. The position for impressing the ultrasonic wave is to be within 3m below the meniscus, because invading depth of the blow hole and the non-metallic inclusion caught in the molten steel pool is within about 3m from the meniscus. By this method, while blowing the inert gas, the trap of the blow hole and the non-metallic inclusion into the interface between solid and liquid is prevented and bulging defect of the product can be sharply reduced.

Title: Heat treatment for semiconductor substrate
Inventor: KITAKATA MAKOTO
IPC: H01L21/322
Filed: 1988-03-28
Abstract: PURPOSE:To make possible a reduction in a heat-treating time and the control of an internal defect by a method wherein the first heat treatment of a substrate is conducted at a specified temperature for a specified time in a non-oxidizing atmosphere and the second heat treatment is conducted at a multistage temperature within a specified range for a specified time. CONSTITUTION:In the heat treatment of a substrate for nucleation, a heat treatment is conducted at a treating temperature of 1000 deg.C or higher - 1250 deg.C or lower for one hour or longer in a nitrogen-containing atmosphere as its first heat treatment. Then, a heat treatment is continuously conducted for one hour or longer while a treating temperature is changed at the speed of a temperature rise of 50 deg.C an hour within a treating temperature range of 500-700 deg.C and while the treating temperature is changed at the speed of a temperature rise of 10 deg.C an hour within a treating temperature range of 700-900 deg.C as its second heat treatment. In such a way, the heat treatment is conducted setting a multistage temperature-rise speed in consideration of a temperature dependence for separation of oxygen instead of a heat treatment which is conducted while a treating temperature is made to rise at an equal speed. Thereby, a treating time is significantly shortened and at the same time, defects can be generated uniformly in the interior of the substrate.

IPC: F25B17/12
Filed: 1989-03-29
Abstract: PURPOSE:To improve thermal efficiency during cooling operation and reduce the size of a metallic hydride vessel by bringing atomized an air current into contact with the surface of said metallic hydride vessel. CONSTITUTION:A controller 1 is designed to supply waste gas from a waste gas generator 5 to a metallic hydride vessel 2 while a cooling air absorber 6 is designed to supply an outside air to a metallic hydride vessel 1 and drives an atomizer 7. Therefore, the metallic hydride MH2 in the metallic hydride vessel 2 is heated up to the temperature of waste gas, say, 200 deg.C and turned into a high temperature and high pressure state SA. On the other hand, liquefied particles sprayed by the atomizer 7 are turned into an aerosol state riding on an outside air current supplied from a cooling air absorber 6. The atomized air comes into contact with the surface of the metallic hydride cell 24 in the metallic hydride vessel 1 so that the metallic hydride cell 24 may be cooled. It is, therefore, possible to improve the thermal efficiency of the whole system.

Title: Pileup detecting circuit for gamma-ray detector
Inventor: KISHI HARUO
IPC: G01T1/17
Filed: 1987-03-27
Abstract: PURPOSE:To detect a pileup with high accuracy by removing an input signal which is scattered and mixed when gamma rays which are emitted at random is detected. CONSTITUTION:An integration circuit 10a integrates only the leading edge part of the input signal. An integration circuit 10b integrates information to be analyzed by an analyzer 16 so that it is processed as brightness information actually. For a normal input, a coefficient is set to, for example, 1.1 in consideration of relation handled by a comparator 14 and malfunction due to the statistical variation of the signal and noises and the comparator 14 confirms that Vb<1.1.alpha.Va holds; and the analyzer 16, on the other hand, selects energy and both outputs are passed through an AND gate 18 to obtain a brightness signal and an unblank output. If a pileup is mixed with the input, V'b>1.1.alpha.Va holds. Consequently, the comparator 14 generates no output and any unblank output is therefore not generated.
